I've been having these weird thoughts lately.... Like, is any of this for real... or not? (opening movie plays, Simple and Clean plays in the background)

The darkness may destroy my body, but it can't touch my heart. My heart will stay with my friends. It'll never die!

Although my heart may be weak, it's not alone. It's grown with each new experience. And it's found a home with all the friends I've made. I've become a part of their heart, just as they've become a part of mine. And if they think of me now and then, if they don't forget me, then our hearts will be one. I don't need a weapon. My friends are my power!

The heart may be weak. And sometimes it may even give in. But I've learned... that deep down there's a light that never goes out!

Kairi, remember what you said before? I'm always with you, too! I'll come back to you. I promise!

It doesn't matter how much we see each other, but how much we think of each other.

Forget it! There's no way you're taking Kairi's heart!

[Startled by Kairi's appearance] Whoa! [Sits up] Gimme a break Kairi!

You're not Riku!

Falling... Falling... Into darkness...

No... the Keyblade! It's mine....

Well, whoever you are, let Riku go! Give him back his heart!

Where... where am I? Who are you? Where's Kairi? Riku....

Our hearts are connected.

Another world safe from darkness!

That's the power of the Keyblade!

Oh, yeah? Well you'll see. I'm gonna get out and learn what's out there!

I'm making a necklace of thalassa shells. In the old days, sailors always wore thalassa shells. They were supposed to ensure a safe voyage.

So, suppose you get to another world. What would you do there?

No matter where I go or what I see, I know I can always come back here.

Take this. It's my lucky charm. Be sure to bring it back to me, okay?

Don't ever forget, wherever you go... I'm always with you.

Sora let's take the raft and go! Just the two of us!

Sora, you lazy bum!

This time, I'll protect you!

Maybe.... You know, I was a little afraid at first, but now I'm ready.

I just can't wait. Once we set sail, it'll be great.

Sora, are you really...? No, he can't be! I WON'T LET HIM GO!

Sora, don't ever change.

I know you will!

Maybe... waiting isn't good enough.

Thinking of you, wherever you are. We pray for our sorrows to end, and hope that our hearts will blend. Now I will step forward to realize this wish. And who knows: starting a new journey may not be so hard, or maybe it has already begun. There are many worlds, and they share the same sky - one sky, one destiny.

It's just... I've always wondered why we're here on this island. If there are any other worlds out there, why did we end up on this one? And suppose there are other worlds... then ours is just a little piece of something much greater. So, we could have just as easily ended up somewhere else, right ?

Exactly. That's why we need to go out there and find out. Just sitting here won't change a thing. It's the same old stuff. So let's go.

Thanks to you. If you hadn't come here, I probably would've never thought of any of this. Kairi, thanks.

If two people share one, their destinies become intertwined. They'll remain a part of each other's lives, no matter what. Come on, I know you wanna try it.

The door has opened, Sora! Now we can go to the outside world! Once we step through, we might not be able to come back. We may never see our parents again. There's no turning back. But this may be our only chance. We can't let fear stop us! I'm not afraid of the darkness!

I get to share the paopu fruit with Kairi. Deal? The winner gets to share a paupu with Kairi.

You were just the delivery boy!

Only the Keyblade master can open the door, and change the world.

Giving up already? C'mon Sora, I thought you were stronger than that.

[To Sora] Take care of her.

Fair enough... Mickey.

I have some unfinished business with this puppet.

Possessed by Ansem

Yes. A Keyblade. But unlike yours, this Keyblade holds the power to unlock people's hearts. Allow me to demonstrate... behold!

Now, open your heart, surrender it to the darkness! Become darkness itself!

This world has been connected. Tied to the darkness... soon to be completely eclipsed. There is so very much to learn. You understand so little... A meaningless effort. One who knows nothing can understand nothing.

Open yourself to the darkness. That is all. Let your heart, your being, become darkness itself.

Take a look at this tiny place. To the heart seeking freedom, this island is a prison, surrounded by water. And so this boy sought out to escape from this prison. He sought a way to cross over into other worlds, and he opened his heart to darkness.

Don't bother, your voice can no longer reach him where he is. His heart belongs again to darkness! All worlds begin in darkness, and all so end. The heart is no different. Darkness sprouts within it, it grows, consumes it. Such is its nature. In the end, every heart returns to the darkness whence it came! You see, darkness is the heart's true essence.

So you have come this far, and still you understand nothing. Every light must fade, every heart returns to darkness!

Behold the endless abyss! Within lies the heart of all worlds: Kingdom Hearts! Look as hard as you are able. You'll not find even the smallest glimmer of light. From these dark depths are all hearts born. Even yours. Darkness conquers all worlds!

It is futile... The Keyblade alone cannot seal the Door to Darkness... Kingdom Hearts! Fill me... with the power of darkness.... Supreme darkness!

(last words) Light?! But why?!

Fight

Return to darkness!

Submit!

You insolent little...

Darkness... Now, you weak-hearted fools... Witness REAL power!

My strength returns...What do you hope to accomplish? Do not deny your fear. The final darkness is nigh. (Dark Shadow)

Maleficent: It was reckless to bring her here without at least using a vessel. Remember, relying too heavily on the dark powers could cost you your heart.

(A roar is being heard outside the castle)

Maleficent: A castaway. Though his world perished, his heart did not. When we took the princess from his castle, he apparently followed her here through sheer force of will. But fear not. No harm will come to you. He is no match for your power.

Riku: My power?

Maleficent: Yes, the untapped power that lies within you. Now, child, it's time you awakened that power and realized your full potential.

(Riku unleashed his true power)

(A conversation between Riku and the Beast)

Riku: No vessel, no help from the Heartless... So tell me, how'd you get here?

Beast: I simply believed. Nothing more to it. When our world fell into darkness, Belle was taken from me. I vowed I would find her again no matter what the cost. I believed I would find her. So, here I am. She must be here. I WILL HAVE HER BACK!

Riku: Take her if you can.

(At the Grand Hall...)

Ansem: So, I see the path has emerged at last.

Maleficent: Yes. The Keyhole to the darkness.

Ansem: Unlock it and the Heartless will overrun this world.

Maleficent: What do I care? The darkness holds no power over me. Rather, I will use its power to rule all worlds.

Ansem: Such confidence.

(Ansem summons his Keyblade)

Maleficent: Oh! Impossible! The princesses of heart are all here! It must be her.

Ansem: Without her heart, she will never be able to release her power.

Maleficent: The king's fools are here. I'll deal with them myself. You stay here and guard the princesses.

(Sora and the others arrived at the Grand Hall)

Sora: Kairi! Kairi! Kairi! Open your eyes!

Ansem: It's no use. That girl has lost her heart. She cannot wake up.

Sora: What? You... You're not Riku.

Ansem: The Keyhole cannot be completed so long as the last princess of heart still sleeps.

Sora: The princess...? Kairi's a princess?

Ansem: Yes, and without her power, the Keyhole will remain incomplete. It is time she awakened.

Sora: Whoever you are, let Riku go! Give him back his heart!

Ansem: But first, you must give the princess back her heart.

(Sora is struggling with his heart)

Donald: Sora!

Sora: What's...

Ansem: Don't you see yet? The princess's heart is responding. It has been there all along. Kairi's heart rests within you!

Sora: Kairi... Kairi's inside me?

Ansem: I know all that there is to know.

Sora: Tell me. Who are you?

Ansem: It is I, Ansem, the seeker of darkness.

(Donald runs to stop him but Ansem knocked him out)

Ansem: So, I shall release you now, Princess. Complete the Keyhole with your power. Open the door, lead me into everlasting darkness!

(Ansem is about to strike Sora when suddenly...)

Kairi: Sora!

(Sora blocks his attack with his Keyblade)

Sora: Forget it! There's no way you're taking Kairi's heart!

(Sora sees a young Kairi in the Hollow Bastion library with her grandmother)

Kairi: Where am I?

Kairi's grandmother: Long ago, people lived in peace, bathed in the warmth of light. Everyone loved the light. Then people began to fight over it. They wanted to keep it for themselves. And darkness was born in their hearts. The darkness spread, swallowing the light and many people's hearts. It covered everything, and the world disappeared. But small fragments of light survived... in the hearts of children. With these fragments of light, children rebuilt the lost world. It's the world we live in now. But the true light sleeps, deep within the darkness. That's why the worlds are still scattered, divided from each other. But someday, a door to the innermost darkness will open. And the true light will return. So, listen, child. Even in the deepest darkness, there will always be a light to guide you. Believe in the light, and the darkness will never defeat you. Your heart will shine with its power and push the darkness away. Do you understand, Kairi? Kairi?!

King Mickey's Note: Donald, Sorry to rush off without sayin’ goodbye, nevertheless, there’s big trouble brewin’. Not sure why, but the stars have been blinkin’ out, one by one. And that means disaster can’t be far behind. I hate to leave you all but I’ve gotta go check into it. There’s someone with a “key”—the key to our survival. So I need you and Goofy to find him, and stick with him. Got it? We need that key or we’re doomed! So go to Traverse Town and find Leon. He’ll point you in the right direction. P.S. Would ya apologize to Minnie for me? Thanks, pal.

Sora: So Kairi, what was it like in your home town, like where you grew up?

Captain Hook: And the brat's friends are the king's lackeys. Swoggle me eyes, they're all bilge rats by the look of them.

Oogie Boogie: You're no prize yourself.

Captain Hook: Shut up!

Maleficent: Enough. The Keyblade has chosen him. Will it be he who conquers the darkness? Or will the darkness swallow him? Either way, he could be quite useful....

Tarzan: Tarzan. Tarzan go!

Sora: And I'm Sora. Tarzan go! Sora go-go!

Cloud: The great god of the Underworld is afraid of some kid? Sorry, but my contract says...

Hades: I know! I wrote the contract! You think I don't know what it says?! I know you're only required to take out Hercules in this tournament, but to get to him, you gotta go through that kid first! After all, a couple casualties along the way wouldn't hurt, right?

[Cloud walks away silently]

Hades: Yeesh. Stiffer than the stiffs back home. Still, suckers like him are hard to come by...

Sora: Hey, are you alright?

Cloud: Yeah.

Sora: So... why you go along with him anyway?

Cloud: I'm looking for someone. Hades promised to help. I tried to exploit the power of darkness, but it backfired. I fell into darkness, and I couldn't find the light.

Sora: You'll find it. I'm searching too.

Cloud: For your light?

Sora: *Nods*

[Cloud stands up, hands Sora a Gummi Block]

Cloud: Don't lose sight of it.

Sora: Hey, how about a rematch next time? Fair and square. No dark powers involved!

Sora: You might not hear it, but right now it's loud and clear. And it's telling me you're on the wrong side!

Riku: You'd betray your king?

Goofy: Not on your life! But I'm not gonna betray Sora either.

(After Riku is defeated by Sora)

Riku: Why? It was mine.

Hooded Man: Know this. The heart that is strong and true shall win the Keyblade.

Riku: What? You're saying my heart's weaker than his?

Hooded Man: For that instant, it was. However, you can become stronger. You showed no fear in stepping through the door to darkness. It held no terror for you. Plunge deeper into the darkness, and your heart will grow even stronger.

Maleficent: I'm afraid you're too late. Any moment now, the final Keyhole will be unsealed. This world will be plunged into darkness. It is unstoppable.

Sora: We'll stop it! After coming this far, there's no way we're gonna let that happen!

Maleficent: You poor, simple fools. You think you can defeat me? Me, the mistress of all evil?

(Maleficent is gravely injured after the first battle and possesed Riku arrives)"

Riku: Do you need some help?

Sora: Riku!

Donald: Is that--

Riku: Yes. A Keyblade. But unlike yours, this Keyblade holds the power to unlock people's hearts. Allow me to demonstrate... Behold!

(Riku thrusts his Keyblade into Maleficent's heart)

Maleficent: Wha--

Riku: Now, open your heart, surrender it to the darkness! Become darkness itself!

(Maleficent gains more power)

Maleficent: This is it! This power! Darkness... The true darkness!

(Maleficent use her power and transformed into a dragon)

(After Ansem is beaten)

Sora: A Keyblade that unlocks people's hearts. I wonder...

Goofy: Sora?

(Donald realizes what Sora is thinking)

Donald: SORA!!

(Sora impales himself on the keyblade and releases his heart and the hearts of all the princesses; Kairi awakens)

Kairi: Sora.

(Ansem arrives)

Ansem: So, princess, you have awakened.

(Riku's heart starts to fight back)

Kairi: Riku!

Riku: Run! The Heartless are coming!

(Kairi, Donald, and Goofy start running and a Heartless follows them)

Donald: Hey! Get out of here you Heartless!

Kairi: Wait! Sora?

Final Mix scene

Riku: Sora... Kairi...I'm sorry...Is this... really the end?

(He starts to fade, but forces it to stop)

Riku: I can't disappear just yet. Not until I've met Sora and Kairi one more time...

Mickey (voice): Riku, can you hear me? I'll be with ya soon.

Riku: Who's there?

Mickey (voice): There's another Keyblade. I find it on this side. I've been trying to talk to you all this time, but the darkness in your heart muffled me out.

Riku: I don't know who you are, but... What's happened to me?

Mickey (voice): Your heart may have overcome the darkness, but you can't take back your body. So only your heart was left behind in the side of darkness where the stolen hearts are gathered.

Riku: What should I do?

Mickey (voice): The door of darkness is about to appear...the door which we cannot pass...In order to close it, two keys and two hearts are needed. Maybe you're here for that same reason as I am. I guess you can call it destiny.

Riku: Destiny... You seem to know alot, don't you? Then tell me this one thing, are Sora and Kairi safe?

Mickey (voice): You should be able to feel their hearts. How one perceives their friends is dependent on his own heart.

Riku: Thank you.

Ansem: It is futile. The Keyblade alone cannot seal the door to darkness. Kingdom Hearts! Fill me with the power of darkness... [The Door to Darkness begins to creak open with ominous black smoke seeping out.] Supreme darkness...

Sora: You're wrong. I know now, without a doubt, Kingdom Hearts... is light!

[Light comes out of the Door to Darkness.]

Ansem: Ugh... Li- light... But- but why?

(The group tries in vain to close the Door to Darkness.)

Donald: Hurry!

Sora: I can’t...

Riku: Don’t give up!

(Riku appeares on the other side of the doors.)

Riku: Come on, Sora! Together, we can do it!

Sora: Okay!

(The four try harder to close the door, but the Heartless are approaching.)

Donald: It’s hopeless!

(Light pierces the darkness on Riku's side of the door, destroyng the Heartless. Goofy and Donald gasp as a sillhouette appears.)

'Donald & Goofy: Your Majesty!

Mickey:(Holds his Keyblade up) Now, Sora! Let’s close this door for good!

Donald: Close it, quick!

Sora: But...What'll happen to you two?

Mickey: Don’t worry. There will always be a door to the light.

Goofy: Sora, you can trust King Mickey.

Riku: Now! They’re coming!

Mickey: Donald, Goofy, thank you.

(Sora’s group closes the door. Riku turns to Sora before he is locked inside the realm of darkness.)
